What exactly do you mean by "it doesn't boot completely"? I compared the two dmesg logs, and I see that the "with MSI" log also has the "single" parameter, so it will only boot to single-user mode. The "pci=nomsi" log does not have "single", so it will boot normally. But I guess if you omit both "single" and "pci=nomsi", something still goes wrong? Do you have a log for that case? Bjorn
